Lamp Holders in DuPont™ Crastin® PBT Meet Needs for Reliability, Economical Cost

Leviton's fluorescent lamp holders

Leviton Manufacturing has sharpened its competitive edge with the adoption of DuPont™ Crastin® PBT thermoplastic polyester for fluorescent lamp holders.

“In redesigning thermoset urea parts to use Crastin®, we were able to meet high quality and reliability goals while meeting customer expectations for high-performance materials,” said Scott Mast, engineering manager at Leviton’s plant in West Jefferson, N.C.

Leviton engineers took advantage of the toughness, resilience and high flow of Crastin® and incorporated integral features for snap-fit assembly and lamp locking, thus eliminating metal fasteners and simplifying assembly. Using Crastin® PBT also eliminates runner scrap and deflashing operations routinely required for urea parts.

“DuPont specialists assisted us with solid technical support,” Mast added. “They recommended suitable resin grades and provided valuable input on tooling design and process optimization.”

DuPont™ Crastin® PBT resins selected by Leviton fulfill requirements for toughness, resilience, strength, UV resistance, a V-0 UL94 flammability classification and high molding productivity.

Founded in 1906 and currently celebrating its 100th Anniversary, Leviton produces lamp holders from Crastin® in a variety of styles and sizes for T 5, T 8 and T 12 fluorescent lamps. For more information on these lampholders, and thousands of other Leviton products, visit or call 800-833-3532.
